Product Details:

Designed to clean spaces up to 3,120 sq. ft. in 60 minutes
Combination of a pre-filter, active carbon filter, and HEPA Filter reduces 99.97% of 0.3 micron particles, including pollen and other allergens. It also reduces volatile organic compounds and odor
With its Smart Mode feature, the Airmega automatically adapts to its surroundings by adjusting fan speeds based on the room's air quality; That means your unit is energy efficient without compromising effectiveness
When the air quality in the room remains purified for 30 minutes or more in Eco Mode, the fan will turn off to conserve energy, kicking on again when pollution is detected
When the Airmega's built-in light and pollution sensors detect that the room has been dark and the air clean for 3 minutes, Sleep Mode reduces the purifier's noise and power consumption

Damn I just bought the white one, didn't arrive yet but I think they are shipping it. I wanted the black one. I will try to cancel and get this. Looks much better.

Best deal in a while on the graphite version. Usually it seems they discount the white versions.

This is technically not the smart version. This deal is for the non-s version.

I recommend the smart version (400S) due to the ability to link it to home assistant and other air quality monitors, etc.

For nearly double the money? Not a chance.

Purchased this unit 6 years ago and still running strong. I usually replace the filter once a year. It's crazy how much dust this thing collects in the pre filter screen. Really is no need for a smart version, it just sucks in dust. What else is there to know from your phone ....lol

Agreed. I've had mine since BF of 2019. Pre filter gets a lot of the stuff in my small room.

You do need to run this at medium speed to get a lot of the benefits. Leaving it on auto doesn't seem to pick up as much dust as medium does. I think I read on Wirecutter that for any purifier, it needs to run at a certain CFM to really be effective and running most purifiers on something lower than their respective medium setting doesn't do a whole lot of good.

Dust falls to ground. Purifiers aren't for dust, they are for airborne particles
